Digital Sky Technologies co-founder Yuri Milner, who co-invested in the Goldman-Facebook deal, enviably poised in the middle. DST has been investing early and aggressively in some of the biggest names in the tech bubble boom like Facebook (DST first invested in May 2009), Zynga (the company that makes Farmville and Cityville for Facebook), and Groupon (the dudes that just turned down Google’s $6 billion).

NOTE -Both groupon and Zynga IPO investors lost money as they are now below IPO price.

Digital Sky got particular attention because of its broad control of the Russian Internet. DNI noted that the company is “a dominant force in the Runet,” owning the most popular Websites in the former Soviet Union, including Russia, Ukraine, Kazakhstan, Georgia, and Armenia as well as others in the Czech Republic and Poland. By some estimates it reported “over 70 percent of all page views in the Russian-language Internet are on its companies’ Websites.”

Last month, a private-market transaction of 100,000 shares of Facebook Class B Common Stock priced at $32.00 apiece gave the website a valuation of $80 billion. Two months ago, Facebook was valued at $65 billion, when investment firm General Atlantic reportedly bought 0.1 percent of Facebook by purchasing roughly 2.5 million Facebook shares from former Facebook employees. Three months ago, Kleiner Perkins Caufield & Byers (KPCB) invested $38 million in Facebook, which was only worth 0.00073 percent of the social network, but still resulted in a valuation of $52 billion.
